FACTS (Flexible A.C. Transmission System)

We can use nowadays the benefit of a number of FACTS technologies for improving the transmission Capacity, stability margins of our power network and enhance better power flow, by compensations of Reactive Power which is continuously changing due to variation of loads.

Main technologies are:

Dynamic Shunt Compensation.

  1. SVC (Static Var Compensation)
    TCR (Thyristor Controlled Reactor)
    TSC (Thyristor Switched Capacitor)
    TCR/FC (Thyristor Controlled Reactor/Fixed Capacitor)
    TCR/TSC (Thyristor Controlled Reactor/ Thristor Switched Capacitor)

Series Compensation.

  1. FSC (Fixed Series Compensation)
  2. TCC (Thyristor Controlled Compensation)
